Abstract

The study was conducted to assess the growth performance and feed conversion ratio (FCR) of Oreochromis niloticus fry reared in experimental ponds. A stocking density of 360 fish/decimal with three feeding frequency T1 (four times/day), T2 (three times/day) and T3 (two times/day) was maintained each with three replications. The fry was initially fed at 30% of their body weight and the rate was reduced up to 5% gradually at the final stage. The survival rate was 95.65±0.367, 93.00±0.709 and 90.50±0.707 % in T1, T2 and T3, respectively. The best FCR value was obtained in T1 (0.983±0.0057) and the significantly (p˂0.05) highest fish production was also observed in T1 (65.67±0.52 kg/dec/120 days). At the end of the experiment, the mean weight gain was recorded as 327.49±2.32, 294.55±0.87 and 244.72±2.33 g in T1, T2 and T3, respectively. The highest percent weight gain (%) was observed in T1 (5468.78±38.87) followed by T2 (5167.54±27.13) and T3 (4293.27±17.36). The specific growth rate (SGR) was also highest in T1 (3.48±0.03) while the lowest SGR was found in T3 (3.15±0.01%). The results revealed that feeding frequency effect positively on the growth performance of Tilapia.
